产品介绍
Fingolimod hydrochloride 是一种新型免疫调节剂,是一种 1-磷酸鞘氨醇 (S1P) 拮抗剂,作用于 K562 和 NK 细胞,IC50为 0.033 nM。它诱导 S1P1 的内化,从而抑制 S1P 活性。它被鞘氨醇激酶磷酸化,尤其是被 SK2 磷酸化,从而可与 S1PR1、3、4 和 5 结合

产品描述

Fingolimod, a novel immune modulator, is a sphingosine 1-phosphate (S1P) antagonist (IC50: 0.033 nM in K562 and NK cells).

体外活性

The cultures of K562 and NK cells were incubated in the presence of 2 μM S1P and increasing concentrations of Fingolimod (FTY720). Addition of various concentrations of FTY720 blocked the inhibitory effect of S1P with an IC50 value calculated at 0.033 nM. The combination of S1P with FTY720 did not affect the expression of these molecules on the surface of iDCs. In addition, 10 nM FTY720 when incubated alone exerted no effect on the expression of co-stimulatory molecules [1]. FTY720 was able to reduce excitotoxic neuronal death in vitro. FTY720 negatively modulates p38 MAPK in LPS-activated microglia, whereas it had no effect on JNK1/2 activation [2].

体内活性

Administration of the immunomodulator FTY720 increased serum S1P, improved impaired systolic contractility and activated the PI3K-pathway in the heart. Cardioprotective effects of FTY720 were abolished following administration of an S1P receptor 2 (S1P2) antagonist or a PI3K inhibitor. Sphingosine kinase-2 deficient mice had higher endogenous S1P levels and the LPS/PepG-induced impaired systolic contractility was attenuated in comparison with wild-type mice [3]. Using human ALL xenografts in NOD/SCIDγc(-/-) mice, three Ph(+) human ALL xenografts responded to FTY720 with an 80 ± 12% reduction in overall disease when treatment was commenced early. In contrast, treatment of mice with FTY720 did not result in reduced leukemia compared to controls using four separate human Ph(-) ALL xenografts [4].

细胞实验

DCs or NK cells were incubated at a cell concentration of 1 × 10^6 cells/ml with either media or with 2 μM S1P, 10 nM SEW2871, 10 nM FTY720 or their combinations. DCs were also incubated with 1 μg/ml LPS. After 24 h incubation, the cells were harvested and the cell suspensions were centrifuged at 1,000 × g for 10 min before the supernatants were collected. Detection of the levels of various cytokines and chemokines was carried utilizing the Multi-Analyte ELISArray Kit as described by the manufacturers' user manual [1].

动物实验

This study was carried out on 2-month-old male C57BL/6J mice or sphingosine kinase-2 deficient (SPHK-2?/?) mice weighing 25–30?g, receiving a standard diet and water ad libitum. C57BL/6J wild-type or SPHK-2?/? mice received i.p.-injections of LPS (9?mg/kg)/PepG (1?mg/kg) or its vehicle (0.9% saline). Sham mice were not subjected to LPS/PepG but were otherwise treated in the same way. At 1?h after LPS/PepG challenge, mice were treated with FTY720 (0.1?mg/kg i.v.) or its vehicle (10% DMSO). To elucidate the role of different S1P receptors in the observed effects of FTY720, mice received (45?min after LPS/PepG and 15?min prior to FTY720) the selective phosphatidylinositol 3 (PI3)-kinase inhibitor LY294002 (0.3?mg/kg i.v.) or the selective S1P2 receptor antagonist JTE 013 (1?mg/kg i.v.) or (1?h after LPS/PepG) the selective S1P1 receptor agonist SEW2871 (1?mg/kg i.v.) or vehicle (10% DMSO) [3].
